Abstract

The utility model relates to a GTM high strength transparent electric heating film ceramic electric heater which belongs to the electric heating products and relates to the electric heating field. The new scheme is used to overcome the defect that the electric heating technology has low thermal efficiency, and short service life and pollutes the heated object. The GTM high strength transparent electric heating film ceramic electric heater comprises an inner core which is made from the ceramic and is attached with a GTM electric heating film on the wall, a sheath which is made from the high-temperature plastic, a temperature controller made from the IC element and a cover made from glass (ceramic). The electric heating film directly conducts the heat to the heated object after the power is switched on. The heat efficiency can reach 95 %. The GTM high strength transparent electric heating film ceramic electric heater can save 40 % electricity. The various functions all realize temperature autocontrol. The GTM high strength transparent electric heating film ceramic electric heater is hygeian, and quick and does not have pollution, odour or open flame. The GTM high strength transparent electric heating film ceramic electric heater can be used as the electric cooker and can be used for the chemical and medical industries.

Description

GTM high strength transparent electric heating film ceramic electric heater

The utility model belongs to the electric heater product, relates to the electric-heating technology field.

In technique known, adopt resistance wire and be that the various electric heaters that heater is made are used widely by resistance wire.But with resistance wire and by resistance wire is that the electric-heating technology that heater is made exists four big defectives: the one, and power consumption is high, the heat efficiency is low, the 2nd, the easy oxidation life-span is short, the 3rd, there is naked light dangerous, the 4th, pollute heating object (food or other materials), because existing electric-heating technology all can not make heating object and metal object isolate, metal is subjected to physics for a long time or chemical action may be polluted heating object.After food is contaminated, emblem amount harmful substance will influence health.

Except that above-mentioned resistance wire, also have a kind of electric heater technology that with graphite is the black Electric radiant Heating Film of primary raw material is made also to obtain Preliminary Applications.

But there is open defect in the black Electric radiant Heating Film electric-heating technology that with graphite is primary raw material: the one, and the black Electric radiant Heating Film easily comes off in the poor adhesive force that is heated on the carrier.The black Electric radiant Heating Film is to adopt the physical process of high temperature sintering attached to being heated on the carrier, comes off once scraping with nail, meets the moist water of meeting and also easily comes off, thereby damage easily, and is unreliable.The 2nd, black Electric radiant Heating Film heatproof is low, and heating power surpasses 200 ℃ and just punctures easily, thereby can not be used widely, and is also dangerous.

The purpose of this utility model is the defective that overcomes above-mentioned two kinds of electric-heating technologies, on thermo electric material and structure with new solution.The first changes electric heating material, and with the new thermo electric material replacement electric furnace heating wire of a kind of high-strength transparence Electric radiant Heating Film, this thermo electric material quality is hard, scrape with sharp device not come off quarter, and have good effect in acid caustic corrosion, not oxidation life-span is 10 times of electric furnace heating wire.It two is to change Electric heating, and this high-strength transparence Electric radiant Heating Film is grown directly upon on the chamber wall that pottery (glass) makes, and planar electric heat source and heating container are united two into one, and changing radiant heat transfer be directly to conduct to heat.It three is to use with the diverse pottery of metal (glass) material and is heated container.

Particularly, feature of the present utility model is to comprise the inner core that is attached with the GTM Electric radiant Heating Film on the wall with ceramic material, and this inner core is a container of containing heating object, is again electric heating element, and two kinds of functions are combined as a whole.

An overcoat made from high temperature plastics both can be closed with electric part, played the beautifying and decorating effect again.

A thermostat made from integrated circuit is realized control automatically during in order to the heating different material.

A buckle closure of making of glass (pottery).

Constituted this electric heater by above-mentioned four (or three) (except that buckle closures) with bonding or mechanical bond method.

The efficient of this electric heater can bring up to 95%, than present resistance wire heating means economize on electricity 40%, long 10 times of life-span.This electric heater inner core adopts not bad, safe and reliable, clean, rapid, pollution-free, the flames of anger of refractory ceramics dry combustion method.

Accompanying drawing 1 is the schematic diagram of a kind of version of GTM high-strength transparence electric ceramic electric heater.

Buckle closure 1 is made for the toughened glass material, and inner core 2 is made for refractory ceramics, and overcoat 3 is made for high temperature plastics, inner core and apply mechanically bonding outward or the mechanical means combination, and electronic temperature control box 4 combines with overcoat 3 usefulness mechanical means.Fig. 1 is in conjunction with preceding shape.GTM transparent electric heating film 5 directly is attached on the outer wall of inner core 2, becomes one.Silver-plated compressing tablet 7 directly contacts with silver electrode on the Electric radiant Heating Film 5, and the other end is connected on supply socket 6 places.

Accompanying drawing 2 is an Electric radiant Heating Film circuit distribution map, and silver electrode 1 silver electrode 4 is two leading-out terminals of Electric radiant Heating Film circuit, and silver-plated compressing tablet 7 directly contacts with this terminal among Fig. 1.Insulation shielding wire 4 is kept apart Electric radiant Heating Film 3.

This electric heater directly one of application is as electric cooking appliance.Now made multi-functional automatic temperature-controlled ceramic electric heating pot.Internal diameter 240mm, external diameter 270mm, height overall 157mm, power 1000W.Can realize drying by the fire, bake, explode, boil, stew, rinse, boil in a covered pot over a slow fire multiple functions such as rice.Pollution-free, free from extraneous odour, the flames of anger, health, rapidly, economize on electricity.

Can also be applied in addition make electric heating appliance in chemical industry, pharmaceuticals industry and the laboratory.

Claims

1, a kind of is that thermal source is the electric heater of carrier with the refractory ceramics with GTM high-strength transparence Electric radiant Heating Film, and its feature comprises:

One is attached directly to the inner core of making on the chamber wall that ceramic material makes with the high-strength transparence Electric radiant Heating Film, and this inner core also is the container that holds heating object;

One what make of high temperature plastic material is to prevent to get an electric shock, and has been again the overcoat of decorative appearance effect;
